2. Analysis
Students begin to identify properties of shapes and learn to use appropriate
vocabulary related to properties, but do not make connections between different shapes and their properties. Irrelevant features, such as size or orientation, become less important, as students are able to focus on all shapes within a class. They are able to think about what properties make a rectangle. Students at this level are able to begin to talk about the relationship between shapes and their properties.

Suggestions for Analysis
 | shifting from simple identification to properties, by using concrete or virtual models to define, measure, observe, and change properties
| | using models and/or technology to focus on defining properties, make property lists, and discuss sufficient conditions to define a shape
| | doing problem solving, including tasks in which properties of shapes are important components classifying using properties of shapes
